gbuild-to-ide: testVS2013Ide add a function that create .filters file

this patch writes the .filters file, it creates 2 filters:
-headers: place, for each module, the header files contained in gbuilparser.modules[<module>][headers]
-sources: place, for each module, the cxx files contained in gbuildparser.modules[<module>][<target>]['CXXOBJECTS']
